The World's Most Bizarre 'Time Zone Delta': Walk Three Steps and Jump 2.5 Hours Ahead

In the Wakhan Corridor, where China, Afghanistan, and Tajikistan meet: China uses the uniform Beijing Time (UTC+8). Afghanistan uses Afghanistan Time (UTC+4:30). Despite bordering each other by land, the time difference between the two countries is a staggering 3.5 hours! This is the largest single time zone difference across any adjacent land border in the world. As soon as you step from Afghanistan into China across the border, you have to immediately set your watch forward by 3 hours and 30 minutes.
